On 6 July 2011 the First Officer of a Ryanair Boeing 737-800 was suddenly incapacitated during a passenger flight from Pisa to Las Palmas. The Captain declared a medical emergency’ and identified the First Officer as the affected person before diverting uneventfully to Girona. The subsequent investigation focused particularly on the way the event was perceived as a specifically medical emergency rather than also being an operational emergency as well as on the operator procedures for the situation encountered.
